Save the following code as a C program called aio.c, then a simple "gcc aio.c -o aio" will compile it. A return value of 1 (one) confirms AIO is available. I run this on Solaris but it should work on HP. Code is followed by an example run:

11978:oracle_at_bart> cat aio.c
#include <unistd.h>
#include <stdio.h>

main()
{ printf("%ld\n", sysconf(_SC_ASYNCHRONOUS_IO)); }

11978:oracle_at_bart> aio
1

Hi everyone -

I am running on a unix server - HP-UX, version 11.0. How can I tell if async i/o is turned on?

Thanks -
Lisa
